Fault codes!!!

Had a few problems for a few months with misfires and limp modes being triggered. No codes however, until today got the following:

29F4 Catalytic converter conversion
29F5 Catalytic converter conversion 2
2D18 manipulation cover, maximum air mass
2F71 E-box-fan, input signal
3100 low boost mode engaged -- CEL displayed
0000 Failure location not implemented

Cat codes are from the Catless DPs
eBox fan has been there a while but sounds like not a big deal..

So 2D18? Could this be a MAF/MAP sensor having a hissy fit?

Any helps is much appreciated...

I think 2D18 is a tuner code

- O2 cat codes
- Tuner code
- ECU fan issue (maybe your USB cable is blocking the fan and AFAIK there two holes you can pop the cable through. The top one doesn't block the fan)
- LIMP mode with low boost. Typically caused by another code.

The 0000 code looks odd. Did you try to see what INPA says?

Any shadow codes?

Haven't managed to get Inpa working yet!!

They are the only codes raised by jb4. I don't have a BT cable either!

I should mention that this is on map zero..
